Article Preview

Silver-doped nano-TiO2 photocatalyst were synthesized via a simple hydrothermal route. The samples were characterized by XRD, XPS, FE-SEM and UV-Vis absorption spectrum techniques. Rhodamine B was selected as the model-pollutant to evaluate the photocatalytic activity of the samples. The XRD results indicated that the Ag-doped TiO2 were pure anatase phase. The UV-Vis spectroscopy revealed that the Ag doping can increase the absorption intensity of TiO2 in the visible region, which results in the improving the photocatalytic activity of TiO2 photocatalyst. Photocatalytic experimental results revealed that Ag-doping TiO2 catalyst shows the enhancement photocatalytic activity.
